Any HAMs on the list.

I was thinking. As we have no RS232 port. It might be possible to hack an old bluetooth headset to connect to a Rig. Somehow attach the mic and ear-piece. Then if we can opperate the PTT somehow.

Then we can take the sound input and create some APRS software that creates a POI list for Maemo Mapper. A separate pop up massager for sending and receiving other signals.

I am going to get my N800 later this week. Anyone else want to play with this.

Can we connect both the Headset and a GPS through BlueTooth?

UPDATE:
I have decided to create a Yahoo group. Hildon Ham

I explain what I am thinking a little more clearly. And can gather info/ideas on the subject of Ham Radio applications for Maemo.

Ok If anyone is interested in this PM me. I will give my EMail.

I have pulled apart an old Jabba 250v Bluetooth headset.

Attaching it to the appropriate plug and using the little vibrate connection to trigger the PTT should be easy. All that is required is adapting software on the N800 to send a ring signal whenever it needs to activate the PTT and convert the sound signal.

I will hunt down a spare plug for my VX-7r and experiment.

Hello fellow Ham. I run a Icom IC-91A that I have been using for my UHF repeater connected to Echlink. Not really sure what you are trying to accomplish..73

I have decided to set this up on a Yahoo Group.

Just to gather ideas and experiment.

Feel free to join in.

Has any progress been made on this?

Well, there's been a little discussion over here...

But no actual progress was made. Everyone who knows how to build stuff is too busy; everyone who has time doesn't know how...

I can build the PTT interface between the NIT and the radio, but some software work will have to be done. I like the ring signal idea mentioned above. My original idea was to have the NIT transmit an aditional audio tone, oh lets say ~10KHz, which won't be picked up by the radio when the NIT is sending the PSK warble. On the radio's PTT side we can use a LM567 tone decoder ( http://web.mit.edu/6.115/www/datasheets/LM567.pdf ) tuned to a 10KHz tone, and ground a pin when it hears one.

Worse comes to worse, it wouldn't be the end of the world if we have to manually use a toggle switch to get the radio to flip between RX and TX.

The ring idea might be a little more complex, software side... the tone generator looks easy enough though.

Yes. I'm not a big time coder, but I have no problems designing a NIT-to-Radio interface and publishing its schematics, board layout, parts list, etc.

Look at what I found:
